The one I want to catch in this story is Shinx. It requires 5 to 10K characters. Actual length is 6374
The day was a horrible day to start a journey, the weather being an especially big point for it was chilly and raining. A, being the coward that he was, was running to find shelter from rain. His Turtwig was strolling on the right side of him, enjoying the drizzle, running around for it was eccentric. A also happened to be bad at navigating, and instead wound up in the forest. The forest was different than any other forest A had ever stumbled upon. The rain in the forest never actually hit the ground, and the trees covered the area like a blanket. In addition to this, few Pokémon could actually be seen.
A journeyed farther through the forest, still curious as to why life other than plants were scarce around it. His question would soon be answered, as when he happened upon a cave, at least hundreds of Pokémon were there. Species such as Caterpie, Weedle, Pidgey, Budew, Burmy, and even a Rotom could be found there. All were festive, and A's Turtwig soon joined the celebration. Things begin to make turn for the worse however, and a mere minutes after A and his Turtwig entered the cave, a figure appears.
The figure is blue, and has an oddly shaped rod like part at its end, most likely a tail. Though small, the residents of the cave are mortified. They all scurry out of the cave, until only A and his Turtwig are left inside, except for maybe some Zubat and Koromori that live in the cave. The figure keeps approaching at a small pace, as if it had all the time in the world. After a long while, the figure comes close enough for A to see. He identifies it as a Shinx, an electric type Pokémon that normally lives in plains, not caves.
The Shinx appeared harmless, and A approaches the little Pokémon. Suddenly, the situation turns rotten, and A is quickly hit by a Spark right in his stomache, quickly followed by an Bite, which narrowly hit. Turtwig is quickly called to battle, and A calls for a Tackle. It obeys, and charges at the Shinx, but the Shinx then uses Double Team, making the turtle hit one of the illusions. Shinx then uses Spark, and Turtwig is hit directly. The next move Turtwig uses is Withdraw, and the Shinx uses another Spark. Even with increased defense, Turtwig is hit hard, and faints. With no other choices, A grabs his Turtwig and leaves. He then starts his journey out of the forest.
However, on the way, he meets an old man feeding Pidgey, Starly, and other flying-types. Said old man sees A and asks if it was caused by a Shinx. A replies by saying that it was a Shinx, and the old man begins to tell the tale of it. The Shinx was once a happy Pokémon, spending its days playing in a land far away. Its happy days would soon be over though, as a Trainer soon passed through the land. Since the Shinx was the first Pokémon he saw, he decided to capture it, and did. The Trainer was abusive, and trained Shinx to be powerful through his techniques. These tactics soon transformed Shinx from a carefree Pokémon to a hardcore battler that hated humans.
The Trainer soon caught other Pokémon, and eventually released the Shinx because its strength couldn't keep up with the other Pokémon he had. Upon hearing this story, A and Turtwig decide to go back to the cave the next day so that they can defeat the Shinx and also show that not all humans are bad. During the time between then, A decides to analyze how Shinx battles and use its weaknesses to his advantage. When the next day rolls around, they return to the cave. The Shinx is again there, and begins to attack. A tells his Turtwig to quickly dodge Shinx's attacks. When the Shinx grows tired, he then commands Turtwig to use Tackle. The Pokémon fires itself at the weakened Shinx and topples it over. To finish it off then, A commands Turtwig to use Razor Leaf.
The Shinx faints, but the ground soon shakes with much power. A gigantic hole then opens up, and the Shinx is very close to the hole. It tries to escape but can't, and A tries to help. He however, is too slow, and the hole grows, making Shinx fall in. However, before it can get too far down, Turtwig jumps in and picks the Shinx up on its back. This, however, was a bad move, and both Pokémon end up stumbling into the ever growing pit. By this time, A manages to be close to the hole. He manages to grab Turtwig and Shinx and toss them out of the hole, but manages falling in himself. At this time, the residing Zubat and Koromori come and begin to haul A up until he's back on the ground. The three then run as fast as they can out of the cave with A in the middle and the two Pokémon on both sides of him. The three stop near the edge of the forest, and A and Turtwig begin to leave.
However, at this time, A decides to battle Shinx and capture it before he leaves. He throws the one Oran berry he has and Shinx eats it. Turtwig also heals itself using Synthesis. The Shinx understands what it is going on, and starts off the fight with Discharge, cleverly glowing to disturb Turtwig's view. Turtwig quickly dodges and uses Razor Leaf. All but one miss, and to reiterate, Shinx then uses Crunch. Seeing an opportunity, Turtwig dodges and uses Absorb. It then uses Razor Leaf while Shinx is trying to recover from the damage.
However, the Shinx is tough. It withstands both attacks and is still going strong. It then uses a weird move that A has never seen before. Suddenly, Turtwig becomes stronger. But then, it starts becoming dizzy, ramming into the surroundings. It uses Tackle, and hits A, knocking him down. The Shinx then uses Discharge again, and Turtwig is hit directly. It tries to use absorb, but hits the ground. This ends up being a good thing for A, however, as it begins making a small rut under Shinx's feet. A tells Turtwig to keep doing so, and it obeys despite not even hearing A. At this time, the confusion is let off, but Turtwig keeps absorbing the ground. The rut then opens under Shinx, and it falls into it. A next commands Turtwig to use Razor Leaf again. Shinx is hit, but, even then, still has enough energy to fight. Turtwig tries to pounce on it, but the Shinx uses Roar, and he is sent flying. It hits the ground shell side up, and Shinx lunges at it. As a last resort then, Turtwig uses Razor Leaf again. Shinx is hit, and severely weakened from both the shock and power. Noticing that it is weak enough at this point, A then throws the Poké Ball, and it starts to rumble...
